The SR 520 bridge crosses Lake Washington (a large lake separating Seattle to the West, and the Microsoft Headquarters in Redmond to the East). The 520 Bridge has been around a while, and the State is looking to rebuild/replace the bridge, add light rail, and generally help one of the biggest traffic bottlenecks in the area.
I don't know of anyone in Washington that would not like a bigger, wider, more easily traversed bridge across Lake Washingon. That is why I am somewhat curious as to why the Washington State Department of Transportation has decided to release some horror films showing the disasters that would befall the bridge if we suffered high winds or an earthquake. We get it! Traffic would suck more than it already does! Put it up for a vote already! ;)
